The St. Louis-based team of Marshall Haas and Jon Wheatley are selling classic, quality-made hardbound notebooks. But there’s more. After you finish taking notes in their Mod Notebook, you mail it to the company using a prepaid envelope found in the notebook’s back pocket. All the pages in the notebook then get scanned, digitized and uploaded to a Mod app and — if you wish — your Evernote, Dropbox, or OneNote accounts.

“We love paper, we love digital storage, and this bridges the two worlds,” Haas says.

Why create a paper-based product in an age of apps? The founders say their hunch is that there’s still something attractive about the tactile experience of handwriting on paper.
